| Abstract: | For a class of discrete-time system, a variable structure control design method is proposed. To reduce the chattering of discrete-time sliding mode control, the reaching law is constructed. A variable structure controller is designed, which can weaken the chattering, improve the control quality, control system close to the origin diminishingly, and make the system stable. The numerical results and simulation examples are given. |
